This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution). It offers a holding torque of 1 kg-cm (14 oz-in), and each phase draws 1 A at 4.5 V. This stepper motor˙s flat profile (16 mm including the shaft) allows it to be used in places where more traditional stepper motors would be too bulky.
Overview
This pancake bipolar stepping motor from Sanyo has a 1.8° step angle (200 steps/revolution) and a holding torque of 1 kg-cm (14 oz-in). Each phase draws 1 A at 4.5 V. The motor has four color-coded wires terminated with bare leads: red and yellow connect to one coil; orange and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver. For more information, see the datasheet (352k pdf).
Our 5mm universal mounting hub can be used to mount objects on the stepper motor˙s 5mm-diameter output shaft.
